Effectiveness validation of a novel comprehensive classification for intertrochanteric fractures / 中国修复重建外科杂志

OBJECTIVE@#To validate the effectiveness of a novel comprehensive classification for intertrochanteric fracture (ITF).@*METHODS@#The study included 616 patients with ITF, including 279 males (45.29%) and 337 females (54.71%); the age ranged from 23 to 100 years, with an average of 72.5 years. Two orthopaedic residents (observers Ⅰ and Ⅱ) and two senior orthopaedic surgeons (observers Ⅲ and Ⅳ) were selected to classify the CT imaging data of 616 patients in a random order by using the AO/Orthopaedic Trauma Association (AO/OTA) classification of 1996/2007 edition, the AO/OTA classification of 2018 edition, and the novel comprehensive classification method at an interval of 1 month. Kappa consistency test was used to evaluate the intra-observer and inter-observer consistency of the three ITF classification systems.@*RESULTS@#The inter-observer consistency of the three classification systems evaluated by 4 observers twice showed that the 3 classification systems had strong inter-observer consistency. Among them, the κ value of the novel comprehensive classification was higher than that of the AO/OTA classification of 1996/2007 edition and 2018 edition, and the experience of observers had a certain impact on the classification results, and the inter-observer consistency of orthopaedic residents was slightly better than that of senior orthopaedic surgeons. The intra-observer consistency of two evaluations of three classification systems by 4 observers showed that the consistency of the novel comprehensive classification was better for the other 3 observers, except that the consistency of observer Ⅳ in the AO/OTA classification of 2018 version was slightly higher than that of the novel comprehensive classification. The results showed that the novel comprehensive classification has higher repeatability, and the intra-observer consistency of senior orthopaedic surgeons was better than that of orthopaedic residents.@*CONCLUSION@#The novel comprehensive classification system has good intra- and inter-observer consistency, and has high validity in the classification of CT images of ITF patients; the experience of observers has a certain impact on the results of the three classification systems, and those with more experiences have higher intra-observer consistency.

Proximal femoral nail anti-rotation versus locking proximal femoral plate for osteoporotic unstable intertrochanteric fractures in senile patients / 中国组织工程研究

BACKGROUND: Senile intertrochanteric fracture is characterized as aging, instability, more complications and high mortality, so choosing an appropriate internal fixation method is critical.OBJECTIVE: To compare the curative efficacy of proximal femoral nail anti-rotation and locking proximal femoral plate for senile osteoporotic patients with unstable intertrochanteric fractures.METHODS: Sixty elderly patients with unstable intertrochanteric fractures were enrolled, and the clinical data were collected. They were randomized into treatment and control groups (n=30 per group), and subjected to internal fixation using proximal femoral nail anti-rotation and locking proximal femoral plate, respectively. The operative indexes,functional recovery and complications were observed in the two groups RESULTS AND CONCLUSION: (1) The incision length, operation time, intraoperative blood loss and time of weight bearing in the treatment group were significantly less than those in the control group (P < 0.01). (2) Harris hip scores in the treatment group were significantly higher than those in the control group (P < 0.05). (3) The incidence of complications in the treatment group was obviously lower than that in the control group. (4) To conclude, the proximal femoral nail anti-rotation exhibits satisfactory treatment outcomes in the internal fixation of unstable intertrochanteric fractures.
